ABSTRACT:
A burn-in apparatus includes a robot for supplying and removing burn-in boards. The robot includes a movable enclosure capable of temperature control. In a burn-in board removing method, a burn-in board which is to be removed from the chamber of a burn-in apparatus body is enclosed by the movable enclosure of the robot. The interior of the movable enclosure is then cooled to normal temperatures by means of a cooling mechanism. Subsequently, power supply to semiconductor IC's on the burn-in board is suspended, and the burn-in board is removed. In this way, disappearance of failures generated by the charging-up during the burn-in can be prevented, and a burn-in test can be accurately conducted.
